Substitution
-2x+8=x^2-9x+18
x^2-7x+10=0
Factoring, we get
(x-5)(x-2)=0
x=5, x=2
If x equals 5,
y=-2(5)+8=
-10+8=
-2
Therefore, we derive our first solution:
<h2><u><em>
x=5,</em></u></h2><h2><u><em>
y=-2</em></u></h2>
Now we solve for our second x
If x=2,
y=-4+8=
4
Therefore, we derive our second solution:
<h2><u><em>
x=2</em></u></h2><h2><u><em>
y=4</em></u></h2>
<u><em></em></u>

Do u need a table or graph if a graph is needed then it have to include customer satisfaction and popularity over time as with the offers included bar/line graph if u wanna go on popularity use a pie chart
Answer:
Diameter: 4
Radius: 2
Equation: ( x-3 ) + ( y + 2) = 4
8(x-3)=8x-24
8x-24=8x-24
8x=8x
x=x
Since x just has to equal itself and not a specific number, there are C, infinitely many solutions to this equation.
